XmToggleButton(3X)XmToggleButton(3X)NAMEXmToggleButton — The ToggleButton widget class
SYNOPSIS
#include <Xm/ToggleB.h>
VERSION
This page documents version 1.2 of the Motif library.
DESCRIPTION
ToggleButton sets nontransitory state data within an application. Usu‐
ally this widget consists of an indicator (square or diamond) with
either text or a pixmap on one side of it. However, it can also con‐
sist of just text or a pixmap without the indicator.
The toggle graphics display a 1-of-many or N-of-many selection state.
When a toggle indicator is displayed, a square indicator shows an N-of-
many selection state and a diamond indicator shows a 1-of-many selec‐
tion state.
ToggleButton implies a selected or unselected state. In the case of a
label and an indicator, an empty indicator (square or diamond shaped)
indicates that ToggleButton is unselected, and a filled indicator shows
that it is selected. In the case of a pixmap toggle, different pixmaps
are used to display the selected/unselected states.
The default behavior associated with a ToggleButton in a menu depends
on the type of menu system in which it resides. By default, BSelect
controls the behavior of the ToggleButton. In addition, BMenu controls
the behavior of the ToggleButton if it resides in a PopupMenu system.
The actual mouse button used is determined by its RowColumn parent.
To accommodate the toggle indicator when created, Label's resource XmN‐
marginLeft may be increased.
Classes
ToggleButton inherits behavior and resources from Core, XmPrimitive,
and XmLabel Classes.
The class pointer is xmToggleButtonWidgetClass.
The class name is XmToggleButton.
New Resources
The following table defines a set of widget resources used by the pro‐
grammer to specify data. The programmer can also set the resource val‐
ues for the inherited classes to set attributes for this widget. To
reference a resource by name or by class in a .Xdefaults file, remove
the XmN or XmC prefix and use the remaining letters. To specify one of
the defined values for a resource in a .Xdefaults file, remove the Xm
prefix and use the remaining letters (in either lowercase or uppercase,
but include any underscores between words). The codes in the access
column indicate if the given resource can be set at creation time (C),
set by using XtSetValues (S), retrieved by using XtGetValues (G), or is
not applicable (N/A).

Specifies the list of callbacks called when the ToggleButton is armed.
To arm this widget, press the active mouse button while the pointer is
inside the ToggleButton. For this callback, the reason is XmCR_ARM.
Specifies the list of callbacks called when ToggleButton is disarmed.
To disarm this widget, press and release the active mouse button while
the pointer is inside the ToggleButton. This widget is also disarmed
when the user moves out of the widget and releases the mouse button
when the pointer is outside the widget. For this callback, the reason
is XmCR_DISARM. Fills the indicator with the color specified in XmNse‐
lectColor and switches the top and bottom shadow colors when set to
True. Otherwise, it switches only the top and bottom shadow colors.
The default is set to the value of XmNindicatorOn. When XmNindicatorOn
is False, and XmNfillOnSelect is set explicitly to True, the background
is filled with the color specified by XmNselectColor. Specifies that a
toggle indicator is drawn to one side of the toggle text or pixmap when
set to True. When set to False, no space is allocated for the indica‐
tor, and it is not displayed. If XmNindicatorOn is True, the indicator
shadows are switched when the button is selected or unselected, but,
any shadows around the entire widget are not switched. However, if
XmNindicatorOn is False, any shadows around the entire widget are
switched when the toggle is selected or unselected. Sets the size of
the indicator. If no value is specified, the size of the indicator is
based on the size of the label string or pixmap. If the label string
or pixmap changes, the size of the indicator is recomputed based on the
size of the label string or pixmap. Once a value has been specified
for XmNindicatorSize, the indicator has that size, regardless of the
size of the label string or pixmap, until a new value is specified.
Specifies if the indicator is a 1-of or N-of indicator. For the 1-of
indicator, the value is XmONE_OF_MANY. For the N-of indicator, the
value is XmN_OF_MANY. The N-of-many indicator is square. The 1-of-
many indicator is diamond shaped. This resource specifies only the
visuals and does not enforce the behavior. When the ToggleButton is in
a RadioBox, the default is XmONE_OF_MANY; otherwise, the default is
XmN_OF_MANY. Allows the application to specify what color fills the
center of the square or diamond-shaped indicator when it is set. If
this color is the same as either the top or the bottom shadow color of
the indicator, a one-pixel-wide margin is left between the shadows and
the fill; otherwise, it is filled completely. This resource's default
for a color display is a color between the background and the bottom
shadow color. For a monochrome display, the default is set to the
foreground color. To set the background of the button to XmNselect‐
Color when XmNindicatorOn is False, the value of XmNfillOnSelect must
be explicitly set to True. Specifies a pixmap used as the button face
when the ToggleButton is selected and the button is insensitive if the
Label resource XmNlabelType is set to XmPIXMAP. If the ToggleButton is
unselected and the button is insensitive, the pixmap in XmNlabelInsen‐
sitivePixmap is used as the button face. If no value is specified for
XmNlabelInsensitivePixmap, that resource is set to the value specified
for XmNselectInsensitivePixmap. Specifies the pixmap to be used as the
button face if XmNlabelType is XmPIXMAP and the ToggleButton is
selected. When the ToggleButton is unselected, the pixmap specified in
Label's XmNlabelPixmap is used. If no value is specified for XmNla‐
belPixmap, that resource is set to the value specified for XmNselect‐
Pixmap. Represents the state of the ToggleButton. A value of false
indicates that the ToggleButton is not set. A value of true indicates
that the ToggleButton is set. Setting this resource sets the state of
the ToggleButton. Specifies the amount of spacing between the toggle
indicator and the toggle label (text or pixmap). Specifies the list of
callbacks called when the ToggleButton value is changed. To change the
value, press and release the active mouse button while the pointer is
inside the ToggleButton. This action also causes this widget to be
disarmed. For this callback, the reason is XmCR_VALUE_CHANGED. Indi‐
cates that the toggle indicator is visible in the unselected state when
the Boolean value is True. When the ToggleButton is in a menu, the
default value is False. When the ToggleButton is in a RadioBox, the
default value is True.

Translations
XmToggleButton includes translations from Primitive. Additional XmTog‐
gleButton translations for buttons not in a menu system are listed
below. These translations may not directly correspond to a translation
table.
Note that altering translations in #override or #augment mode is unde‐
fined. BDragPress: ProcessDrag() BSelect Press: Arm() BSelect

Additional XmToggleButton translations for ToggleButtons in a menu sys‐
tem are listed below. In a Popup menu system, BMenu also performs the
BSelect actions. These translations may not directly correspond to a
translation table. BSelect Press: BtnDown() BSelect Release:BtnUp()

Action Routines
The XmToggleButton action routines are described below: If the button
was previously unset, this action does the following: If XmNindicatorOn
is True, it draws the indicator shadow so that the indicator looks
pressed; if XmNfillOnSelect is True, it fills the indicator with the
color specified by XmNselectColor. If XmNindicatorOn is False, it
draws the button shadow so that the button looks pressed. If XmNlabel‐
Type is XmPIXMAP, the XmNselectPixmap is used as the button face.
Calls the XmNarmCallback callbacks.
If the button was previously set, this action does the following: If
both XmNindicatorOn and XmNvisibleWhenOff are True, it draws the indi‐
cator shadow so that the indicator looks raised; if XmNfillOnSelect is
True, it fills the indicator with the background color. If XmNindica‐
torOn is False, it draws the button shadow so that the button looks
raised. If XmNlabelType is XmPIXMAP, the XmNlabelPixmap is used as the
button face. Calls the XmNarmCallback callbacks. If the ToggleButton
was previously set, unsets it; if the ToggleButton was previously
unset, sets it.
In a menu, does the following: Unposts all menus in the menu hierarchy.
Unless the button is already armed, calls the XmNarmCallback callbacks.
Calls the XmNvalueChangedCallback and XmNdisarmCallback callbacks.
Outside a menu, if the button was previously unset, this action does
the following: If XmNindicatorOn is True, it draws the indicator shadow
so that the indicator looks pressed; if XmNfillOnSelect is True, it
fills the indicator with the color specified by XmNselectColor. If
XmNindicatorOn is False, it draws the button shadow so that the button
looks pressed. If XmNlabelType is XmPIXMAP, the XmNselectPixmap is
used as the button face. Calls the XmNarmCallback, XmNvalueChanged‐
Callback, and XmNdisarmCallback callbacks.
Outside a menu, if the button was previously set, this action does the
following: If both XmNindicatorOn and XmNvisibleWhenOff are True, it
draws the indicator shadow so that the indicator looks raised; if XmN‐
fillOnSelect is True, it fills the indicator with the background color.
If XmNindicatorOn is False, it draws the button shadow so that the but‐
ton looks raised. If XmNlabelType is XmPIXMAP, the XmNlabelPixmap is
used as the button face. Calls the XmNarmCallback, XmNvalueChanged‐
Callback, and XmNdisarmCallback callbacks. This action unposts any
menus posted by the ToggleButton's parent menu, disables keyboard tra‐
versal for the menu, and enables mouse traversal for the menu. It
draws the shadow in the armed state and, unless the button is already
armed, calls the XmNarmCallback callbacks. This action unposts all
menus in the menu hierarchy. If the ToggleButton was previously set,
unsets it; if the ToggleButton was previously unset, sets it. It calls
the XmNvalueChangedCallback callbacks and then the XmNdisarmCallback
callbacks. Calls the callbacks for XmNdisarmCallback.
In a Pulldown or Popup MenuPane, unposts all menus in the menu hierar‐
chy and restores keyboard focus to the widget that had the focus before
the menu system was entered. Calls the callbacks for XmNhelpCallback
if any exist. If there are no help callbacks for this widget, this
action calls the help callbacks for the nearest ancestor that has them.
In a toplevel Pulldown MenuPane from a MenuBar, unposts the menu, dis‐
arms the MenuBar CascadeButton and the MenuBar, and restores keyboard
focus to the widget that had the focus before the MenuBar was entered.
In other Pulldown MenuPanes, unposts the menu.
In a Popup MenuPane, unposts the menu and restores keyboard focus to
the widget from which the menu was posted. Drags the contents of a
ToggleButton label, identified by pressing BDrag. This action creates
a DragContext object whose XmNexportTargets resource is set to "COM‐
POUND_TEXT" for a label type of XmSTRING; otherwise, "PIXMAP" if the
label type is XmPIXMAP. This action is undefined for ToggleButtons
used in a menu system. If the pointer is within the button, takes the
following actions: If the button was previously unset, sets it; if the
button was previously set, unsets it. Calls the XmNvalueChangedCall‐
back callbacks.
Additional Behavior
This widget has the additional behavior described below: In a menu, if
keyboard traversal is enabled, this action does nothing. Otherwise, it
draws the shadow in the armed state and calls the XmNarmCallback call‐
backs.
If the ToggleButton is not in a menu and the cursor leaves and then
reenters the ToggleButton's window while the button is pressed, this
action restores the button's armed appearance.
In a menu, if keyboard traversal is enabled, this action does nothing.
Otherwise, it draws the shadow in the unarmed state and calls the
XmNdisarmCallback callbacks.
If the ToggleButton is not in a menu and the cursor leaves the Toggle‐
Button's window while the button is pressed, this action restores the
button's unarmed appearance.
